Abstract
The utility model discloses a multi-bit drill which consists of a knife shaft gear, a knife shaft, an intermediate gear, a central gear, a taper shank shaft, an inner gear ring, an outer gear ring, a casing and a connection flange and is characterized in that the knife shaft gear is connected with a knife shaft key; the central gear is connected with a taper shank shaft key; outer teeth of the inner gear ring and the outer gear ring are meshed with the knife shaft gear, and inner teeth of the inner gear ring and the outer gear ring are meshed with the intermediate gear; the intermediate gear is meshed with the central gear; a plurality of shafts are fixed by the casing through bearings; and the casing is connected with an angular milling head of a floor type boring and milling machine through the connection flange. The multi-bit drill has the advantages of novel gear transmission structure, small transmission ratio, less effect on the torque of the annular milling head, simple structure, good technics and high processing efficiency and not only can finish the processing of a plurality of holes at one time, but also can reduce the occupied man-hour to a large-scale milling and boring machine.
Description
Technical field
The utility model relates to parts or the annex that is specially adapted for boring machine or drilling machine, relates in particular to have one or more working shafts the additional gear transmission device that is connected with main working shaft.
Background technology
The number of bolt holes in flange amount of large-scale workpiece is many, and the positional precision of requirement is very high, and processing is relatively wasted time and energy.With drilling machine or boring machine processing, can only process a hole in the tradition processing, working (machining) efficiency is lower at every turn.And be difficult for to guarantee with drilling machine Working position precision; Lower with numerical control floor boring machine working (machining) efficiency, processing cost is higher.So, generally speaking,, can make special equipment and process for some bigger in batches workpiece.And for certain batch is arranged but be not suitable for making the large-scale workpiece of special equipment, will meet difficulty.Therefore, develop a kind of multi-bit drilling tool that can be installed on the equipment such as floor type boring machine,, have important practical significance in order to improve the efficient and the precision in machining large workpiece flange bolt hole.
Summary of the invention
Goal of the invention of the present utility model is, designs a kind of multi-bit drilling tool that can be installed on the equipment such as floor type boring machine, is intended to the whole bolts hole that machine the large-sized flange requirement by disposable.
Technical solution of the present utility model is achieved in that
A kind of multi-bit drilling tool is made up of knife shaft gear, cutter shaft, idle wheel, central gear, taper-shank arbor, interior external toothing, shell, adpting flange, and it is characterized in that: knife shaft gear and cutter shaft link together by key; Central gear and taper-shank arbor link together by key; The external tooth and the knife shaft gear of interior external toothing are meshed; The internal tooth and the idle wheel of interior external toothing are meshed; Idle wheel and central gear are meshed; Shell is fixing with each axle by bearing; Shell then is connected by the angular milling head of adpting flange and floor-type milling ﹠ boring machine.
Compared with prior art, advantage of the present utility model is apparent, mainly shows:
1, can be installed in easily on the conventional equipments such as floor type boring machine and process, improve the hole machining accuracy.
2, drilling tool gear transmission structure novelty, gearratio is little, and diagonal angle milling head torque influence is little;
3, simple in structure, low cost of manufacture;
4, once can finish the processing of a plurality of holes, easy to operate, good manufacturability.Drilling efficiency can be significantly improved, the man-hour that takies can be significantly reduced again large-scale boring and milling equipment.
Description of drawings
The utility model drawings attached 3 width of cloth, wherein:
Fig. 1 is the structural representation of the utility model multi-bit drilling tool;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the kinematic sketch of mechanism of the utility model multi-bit drilling tool.
In the drawings: 1, knife shaft gear, 2, cutter shaft, 3, idle wheel, 4, central gear, 5, taper-shank arbor, 6, interior external toothing, 7, shell, 8, adpting flange.
The specific embodiment
As Fig. 1～a kind of multi-bit drilling tool shown in Figure 3, to form by parts such as knife shaft gear 1, cutter shaft 2, idle wheel 3, central gear 4, taper-shank arbor 5, interior external toothing 6, shell 7, adpting flanges 8, knife shaft gear 1 and cutter shaft 2 link together by key; Central gear 4 and taper-shank arbor 5 link together by key; The external tooth of interior external toothing 6 and knife shaft gear 1 are meshed; The internal tooth of interior external toothing 6 and idle wheel 3 are meshed; Idle wheel 3 and central gear 4 are meshed; Shell 7 is fixing with each axle by bearing; Shell 7 is connected with the angular milling head by adpting flange 8.Its course of work is as follows: the angular milling head of multi-bit drilling tool by adpting flange 8 and boring machine is connected.The taper hole of taper-shank arbor 5 and angular milling head connects, and connects fastening with bolt.Power during work is passed to taper-shank arbor 5 by the angular milling head, and taper-shank arbor 5 is passed to central gear 4 with power; Central gear 4 is passed to cutter shaft 2 by the idle wheel 3, interior external toothing 6 and the knife shaft gear 1 that are meshed with power.Drill bit can be installed on the cutter shaft to be processed.A plurality of cutter shafts can evenly distribute on circumference, also can uneven distribution.When taper-shank arbor rotates, many cutter shafts will rotate together and process.The feeding of multi-bit drilling tool and withdraw from and to control by the motion of boring machine.Multi-bit drilling tool can load and unload easily and uses as a cutter, and this multi-bit drilling tool is good once to bore 6～24 holes.
